A tank with a square base of 40 cm was
38 filled with water After another 17600 cm
3 of water was poured into the tank, it became
56 full.
- Find the capacity of the tank in litres.
- Find the final height of the water in the tank.
(a)
Fraction of the tank when 17600 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 17600
124 of the tank = 17600 ÷ 11 = 1600
2424 of the tank = 24 x 1600 = 38400
38400 mℓ = 38.4 ℓ
Capacity of the tank = 38.4 ℓ
(b)
2024 of the tank = 20 x 1600 = 32000
Final height of the water in the tank
=
3200040 x 40 = 20 cm
Answer(s): (a) 38.4 ℓ; (b) 20 cm
